Assistive technology (AT) is a service or device that provides individuals with polytrauma injuries the chance to engage in their daily activities. AT specialists use the Human Activity Assistive Technology frame of reference to guide their evaluation, treatment, selection, and training process as it also takes into account the context in which AT devices would be used. AT devices include augmentative and alternative communication, electronic cognitive devices, wheeled mobility, electronic aides to daily living, adaptive computer access, and adaptive sports. Within all of these areas of AT, other considerations include accessing the devices, mounting the devices, and integrating the technology when possible.
